#organoids.

The wild/feral setup for Organoids involves colonies that nest in a specific spot and they’re loosely led by a handful of “female” Organoids. Like Zoids, Organoids don’t have a set sex. The Organoid(s) in charge of the colony will switch to a female (read: egglaying) role if they weren’t already set up for that. This leadership is usually stable, but anyone can pick a fight with the lead females if they so choose. If someone does this and loses though, they’re gonna have a bad time. If a lead female is defeated, they generally just shrug, switch to a male role and vibe, or if they’re unhappy enough with things they might leave the colony. There’s an unequal ratio of male to female Organoids in wild colonies. The MAJORITY (90%+) take on male roles. Their job is to feed and protect the colony, and spend an ungod amount of time in ritual combat and mating displays to show how awesome they are and should be allowed to fuck the ‘queens.’ The other female Organoids in the colony tend to not be so picky, but their lower social status is known. While they’re allowed to reproduce and not strictly prohibited from it, their eggs and offspring are fair game until they’re old enough to defend themselves. Wild Organoids have no qualms whatsoever about eating offspring that aren’t theirs. Wild Organoids OVERBREED. Like Zoids, they produce a high number of offspring/potential offspring with the assumption that a lot of them will be eaten/won’t make it to adulthood.

However, as Organoids developed tighter and cooperative social structures, the loss of eggs and hatchlings dropped significantly. The evolutionary timeline hadn’t quite caught up with this yet, and the “we’re spreading like wildfire and eating everything that moves” stage of this mess is when they first came into contact (and conflict) with ancient-ancient-Zoidians.  

I’ve gone into the history of “domesticating the Organoid” before so I won’t go into it here, but in ‘modern’ Ancient Zoidian times, the majority of the colonies on Zi were ‘domestic’ Organoids, wild ones were becoming uncommon. They went extinct completely after the Death Saurer. Domestic Organoids still retain wide feral streaks, but their colonies are fundamentally altered because Zoidians disrupted the entire basis for their social structure. The main purpose colonies served at that point in time was to be safe communal nesting grounds. 

The sex ratio of Organoids now mirrored the sex ratio of Zoidians, which is like humans’. Organoids were generally compelled to take on the biological sex of their bondmate, but could switch if the life of the Zoidian in question reflected that.  Many of the smaller Zoidian groups/nations/tribes/clans didn’t get along 100%, so the Organoids did indeed have reason to protect their nesting areas. Often, even if Zoidians managed to avoid direct conflict, their Organoids sometimes wouldn’t. This is part of what kept driving the Zoidians into conflict. This problem also grew a lot in later years, exploited by ill-meaning groups re: the idea that Zoidians generally forgave transgressions driven by Organoids. It was a good-faith effort to indicate they were “the better person” there, a show of their control over their emotions vs. their partner. It takes several days for an Organoid to switch between sex roles, it’s not instant. It’s more a “hormonal” type change than anything physical.

Organoids hatch without any sex role being active, because they’ve not been exposed to anything that’d prompt them one way or the other.

This changing of roles is not something they can necessarily consciously do, and many (domestic) Organoids come to strongly prefer the role of their bondmate to the point they’d maintain it even if their bondmate died. The preference is so solid that it can override wild/feral promptings to the contrary.

Organoids can reproduce as either sex for their entire lives. Which is also true for most Zian creatures. The reproductive ability is rooted in the Core, very literally.

Healthy Organoids of both sexes (who have not recently copulated) regularly produce slugs, aka unfertilized eggs. And literally everyone likes to eat these. Organoids of all ages, and Zoidians alike. Organoids, especially of the domestic sort, for which most survival pressures were greatly reduced or removed entirely became incredibly hedonistic. Some Zoidian groups tended to control the outcomes of this by encouraging “excess” egg consumption, so no maturation/hatching resulted. Some groups just let nature take its course. It was a contentious issue. Organoid/Zoidian families don’t maintain related Organoid offspring. All the eggs were laid/seen to in the colony, and the female Organoid and their bondmate might’ve hung out there for awhile to tend to the hatchlings. Big emphasis on “might” because Organoids can range from incredibly maternal to “shit eggs and run”, which generally’d align with the attitude of their bondmate. Toddler-equivalent Zoidians are basically taken to Organoid colonies to find a young Organoid to bond with. There’s a lopsided maturation difference between Organoids and Zoidians (obviously); Organoids will be much larger than their partners for a bit, but take a while past the Zoidians’ sexual maturity to reach their own. This has to do with how long in general it takes for Zoid Cores (Organoid Cores too) to sufficiently bud. Organoids were intimately involved with Zoidians’ lives and this included their sex lives.  Zoidian families of any arrangement were overwhelmingly likely to have extremely compatible Organoids. The Organoids would often be the ones encouraging their partners to have sex, just by dint of being aroused and drowning their partners in Horny.

Either side could choose to have sex independently, but it was so much better to do it as a group, that more-or-less became the complete norm. In the group, it’s the Zoidians having sex AND the Organoids having sex - they’re not involved ‘across state lines’ so to speak, but the feedback loop between bonded partners is the best kind of crazy.

Needless to say, not having sex this way seemed boring and dumb.

(And now you feel slightly more bad for Shadow’s Immense Predicament.) 

Other details that people probably want for some godforsaken reason: This is the end of an Organoid’s reproductive organ. There’s 6 of them. They’re a little larger than all of the other cabling in their body.

This is how the male and female parts fit together:

The interior of the female’s cabling is basically coated with thick, nutrient-rich jelly that’s not much unlike what’s inside a Zoid core. 

When their own Core buds, the buds eventually break off and go get stuck somewhere in aforementioned jelly. If fertilized, they become eggs, if not fertilized, they become slugs. 

Organoids don’t climax. Their entire experience of copulation reads like a continuous orgasm, as the encouraged behavior is length and quality of connection, not building to anything.

As one might imagine, this is unreasonably amazing for the associated Zoidians, and likewise the presence of pleasurable intercourse leading to climax is wholly foreign to Organoids, who get just as much out of that experience.

Organoids are actually quite into touch, but their most sensitive place by far are little synthflesh areas on their reproductive organs. When locked in with another Organoid, both are receiving direct and continuous pressure. 

Nothing in a human or Zoidian body can offer this. At best, an Organoid can be quite teased by various sphincters, but the real appeal in participating “alone” (read: no 2nd Organoid) in sex is that they can still experience whatever their bondmate is experiencing. In addition to what pleasure they can nab for themselves.

Oh yhea and mutual masturbation is totally a thing.

In addition re: males there also has to be SERIOUS TRUST INVOLVED HERE BECAUSE a fully aroused male Organoid can easily fuck you up:

They also just kind of ooze milt the entire time they’re aroused, and that intensifies if they’re stimulated.
